Randomly selected men are given a Test Prepartion Course before taking this test. Assume, for sake of argument, that the test has no effect. If 1 ofthe men is randomly selected, find the probability that his score is at least 570.1. Enter your answer as a number accurate to 4 decimal places. NOTE: Answers obtained using exact z-scores or zscores rounded to 3 decimal places are accepted. If 20 ofthe men are randomly selected, find the probability that their mean score is at least 570.1. Enter your answer as a number accurate to 4 decimal places. If the random sample of 20 men does result in a mean score of 570.1, is there strong evidence to support the claim that the course is actually effective? O No. The probability indicates that is is possible by chance alone to randomly select a group of students with a mean as high as 570.1. Yes. The probability indicates that is is (highly .7) unlikely that by chance, a randomly selected group of students would get a mean as high as 570.1. 06
